Abstract: ABSTRACT OF THE DISCLOSURE:     A microtome comprises a handwheel which can be ro-tated in two directions of rotation, and drive means for the purpose of driving a specimen holder,  so that the specimen  holder  executes  a  cutting  movement when  the handhweel is rotated in one direction, and a resetting movement when the handwheel is rotated in the other di-rection.  The cutting and resetting movements take place relative to a cutting knife.   A reduction gearing arr-angement enables the speed of the cutting movement to be reduced relative to the speed of the resetting movement without having to rotate the handwheel at a correspond-ingly lower rate.  A catch enables the reduction gearing arrangement to be bridged so that the speed of the cutt-ing movement and resetting movement are equal for any given rate of rotation of the handwheel.

Abstract: Abstract A gray scale image of a fingerprint composed of a field of pixels is converted to a binary image composed of a field of pixels by a technique which takes into account the directivity of the ridge and valley struc-ture.  Three intermediate binary images are developed, one by the use of a vertical filter, one by the use of a horizonal filter and a reference image by the use of a filter which is not directionally biased.  Corresponding subfields around each pixel in each of the three images are compared. If the subfield for the vertically derived image is closer to that of the reference image then is the subfield for the horizonally derived image, then the binary value for the pixel from the vertically derived image is used in the final image; and vice versa. In this fashion, a fourth a final binary image is derived from a combination of the vertically derived image and hori-zonally derived image which includes the best imagery from each of those two intermediate images.

Abstract: ABSTRACT            In contrast with the known method of cleansing surfaces by the projection of sand particles in an air stream against the surface, the present invention proposes to project particles of ice or other frozen liquid at the surface with the result that the spent particles will thereafter melt at the ambient temperature and be readily removed from the site and separated, if necessary, from contaminants dislodged from the surface.  Apparatus according to the invention comprises means for the introduction of ice particles continuously into a stream of pressurised air, preferably mixed with water.  The means may comprise a plurality of containers, each successively passing between a position where they receive ice particles from a supply and a position where they release the particles to the stream.

Abstract: "Synchronization Circuit for Digital Communication Systems"                 ABSTRACT OF THE DISCLOSURE     In a digital communication system, a sync word is generated at intervals at the transmitting end and appended to a data bit stream having redundant bits generated by an error correction encoder.  The sync word indicates the position of the redundant bits in the data bit stream.  At a receiving end of the system, a syndrome generator is responsive to the data bit stream for deriving therefrom a syndrome and applying it to the error corrector to cause it to correct error which may exist in the data bit stream. A word synchronizer detects the sync word contained in one of the syndromes and causes the syndrome generator to establish synchronism with the data bit stream.  The word synchronizer includes a detector for detecting a prescribed set of binary states in the syndromes which indicate that there is no errors in the data bit stream and causing the syndrome generator to generate a syndrome synchronously with data words in the data bit stream.

According to the invention, a specific ID-signal is transmitted to the telephone network during a first predetermined time period after completed switching operation to a specific reply set, with simultaneous monitoring of the telephone network with regard to digits entered from called reply set transferred via the telephone network as a pulsed signal, multi frequency signal or optical signal, absence of such digit entered from the reply set during said first time period resulting in disconnection of the connection.  Detection of one or a number of digits entered from the reply set during said first time period being interpretated as specific commands, which are transformed into specific actions, for example establishment of video and/or speech communication with the entrance set, blocking action preventing repeated calls during a predetermined time period, immediate disconnection, alarm transmission from the entrance set or any other predetermined function.  The first time period is followed by a second time period, provided that a predetermined digit is entered during the first time period, whereunder video and/or speech communication can take place between the reply set and the entrance set.  Digits entered from the reply set during said second time period are detected and interpretated as specific commands, which with regard to resulting function for one or a number of individual signals result in different resulting functions in relation to corresponding signal(s) during the first time period.

Abstract: ABSTRACT OF THE DISCLOSURE An interface system for interfacing a standard telephone set with a radio transceiver as part of a telephone network is provided.  The radio transceiver may be a conventional cellular-type transceiver or other transceiver having typical control inputs and outputs similar to that provided by cellular transceivers. The interface system converts tone-dial or pulse-dial inputs from the telephone into a serial data stream for storage in the transceiver. The interface system automatically determines when the last numeral or digit is dialed and provides a send signal to the transceiver when such determination is made.  The system responds to incoming call signals, such as alert signals, from the transceiver and rings the telephone accordingly. The system simulates ring and dial-tone type signals under conditions typical of standard telephone set usage.
